Nyob hauv peb cov yeeb yaj kiab tshiab ntawm cov khoom noj hauv lub voj voog, peb saib kev ua tau zoo-txhim kho lub zog ntawm beetroot txo hwj chim
Thaum Apollo, Greek vajtswv ntawm (nrog rau lwm yam) tshuaj, tau nthuav tawm nrog beetroot ntawm nws lub tuam tsev hauv Delphi, nws tau tshaj tawm tias nws muaj nqis rau nws qhov hnyav hauv nyiaj rau nws cov khoom kho. Ua tsaug rau tus nqi tau nqis los me ntsis txij thaum ntawd los thiab, thaum tsis yog ib qho txuj ci kho tau zoo, cov zaub no muaj txiaj ntsig ntau rau cov neeg caij tsheb kauj vab.
'Beetroot, zoo li txhua yam zaub, yog qhov muaj ntau cov vitamins thiab minerals uas tuaj yeem pab ua haujlwm thiab rov ua haujlwm, nrog rau muaj cov tswv cuab ntawm phytochemicals suav nrog betalains uas muaj cov tshuaj tua kab mob antioxidant thiab tiv thaiv kab mob, 'hais tias kev ua tau zoo. Nutritionist Drew Nqe.'Qhov kev txaus siab tshwj xeeb rau tus neeg caij tsheb kauj vab, txawm li cas los xij, yog cov tsis muaj nitrates pom hauv beetroot.'
'Cov tshuaj lom neeg hu ua nitrates pom hauv beetroot tau tawg los ntawm koj cov qaub ncaug los ua nitric oxide hauv lub cev, 'hais Nigel Mitchell, tus thawj coj ntawm kev noj haus ntawm Team Sky. 'Nitric oxide pab nrog kev nthuav dav ntawm cov hlab ntsha me, uas txhim kho oxygen thauj mus los nyob ib puag ncig lub cev kom roj cov leeg. Nws kuj pab txo cov ntshav siab, uas yog qhov zoo rau kev noj qab haus huv txawm tias koj tsis yog tus neeg tseem ceeb caij tsheb kauj vab.'
'Muaj ntau qhov kev tshawb fawb uas qhia tias haus beetroot tuaj yeem txhim kho kev ua haujlwm ntawm kev ua haujlwm ntev, ' ntxiv Todd Leckie, cov neeg tseem ceeb triathlete thiab cov tub ntxhais kawm kho mob uas tau tshawb fawb txog cov txiaj ntsig ntawm cov kua txiv beetroot ntawm kev tawm dag zog ua ib feem ntawm nws qib. hauv Applied Exercise Physiology ntawm University of Brighton. 'Ib pawg tshawb fawb ntawm Exeter University tau tsim cov tshuaj nitrate-depleted placebo [los sim tawm tsam beetroot] thiab pom tias nws yog cov ntsiab lus nitrate siab hauv cov kua txiv hmab txiv ntoo uas pab ua haujlwm. Kev tshawb fawb luam tawm hauv Tshuaj & Kev Tshawb Fawb Hauv Kev Ua Si & Kev Ua Si tau pom qhov txo qis hauv 10-mais lub sij hawm sim ntawm 14 vib nas this ntawm cuaj pawg neeg caij tsheb kauj vab. Cov nitric oxide boosts kev ua tau zoo los ntawm kev txhim kho tus neeg ncaws pob kev ua tau zoo - uas yog, txo lub zog yuav tsum tau ua rau tus nqi ua haujlwm.'
Nqe hais tias, 'Beetroot tuaj yeem muaj txiaj ntsig ntau yam. Raws li kev txhim kho hauv lub sijhawm sim, lub sijhawm rau kev qaug zog tuaj yeem nce mus txog 16%. Nitrate kuj txo qis kev nkag siab ntawm kev siv zog thiab lub plawv dhia, thiab tau pom tias yuav ua rau kom muaj zog ntawm cov leeg nqaij. Tag nrho cov no ntxiv rau kev txhim kho kev ua haujlwm. Dab tsi yog qhov pab tau, vim tias koj tuaj yeem tau txais cov neeg caij tsheb kauj vab sib zog ua haujlwm ntawm qhov chaw [ntawm cov tsheb kauj vab zoo li qub], ntau qhov kev tshawb fawb tau ua tiav siv lawv, yog li nws cuam tshuam ncaj qha rau peb.'
No limits
xov xwm zoo yog, thaum nws los noj beetroot, tsis muaj xov xwm phem tiag tiag. 'Koj tuaj yeem muaj nws txhua hnub,' Mitchell hais. 'Tsis muaj qhov teeb meem tiag tiag.'

Tej zaum qhov teeb meem loj tshaj plaws, uas tuaj yeem ua rau muaj kev ntxhov siab ntawm qhov tso zis, yog 'beeturia'. 'Nws tuaj yeem hloov koj cov zis liab liab,' Mitchell hais. 'Nws tseem tuaj yeem pleev xim rau koj cov quav thiab ua rau nws zoo li koj tab tom ua ntshav. Nws tsis txaus ntshai - tib neeg tsuas yog yuav tsum paub tias qhov no tuaj yeem tshwm sim.'
Yog tias koj ntseeg qee yam ntawm cov xov xwm tshaj tawm, beetroot yog 'superfood' uas yuav tsis tsuas yog pab koj yeej lub Tour de France tab sis kuj tseem yuav pab koj nyob kom txog thaum koj muaj 100. Tu siab qhov tseeb tsis yog. ua neej nyob li no xwb.
'Zoo li yuav luag txhua yam zaub mov, beetroots noj qab nyob zoo tab sis "superfood" daim ntawv lo yog ntau yam khoom lag luam tshaj li lwm yam, 'Price hais. 'Yog lawm, nitric oxide muaj qhov cuam tshuam rau kev noj qab haus huv thiab cov phytochemicals ib yam nkaus, tab sis nws tsuas yog ib feem me me ntawm daim duab loj ntawm kev noj haus thiab kev ua neej thiab tej zaum yuav tsis hloov koj mus rau Superman.'

Cia koj cov kua txiv ntws
Hom beetroot feem ntau yog, zoo li John Prescott, puag ncig thiab ntshav. Thiab zoo li yav dhau los tus lwm thawj PM, nws tsis yog ib yam uas koj tuaj yeem nqa nrog koj caij tsheb. Yog li dab tsi yog txoj hauv kev zoo tshaj plaws los noj nws?
'Raws li kua txiv,' hais tias Leckie. 'Koj xav tau tsawg kawg yog 250g - txawm tias tej zaum ze rau 500g - kom tau txais cov nyhuv, yog li cov kua txiv hmab txiv ntoo yog cov neeg siv ntau dua.'
Mitchell tseem pom zoo kom muab nws rau cov pluas noj kom ntxiv koj cov khoom noj. Nws hais tias 'Nws yog qhov zoo tshaj plaws shredded hauv zaub xam lav nrog zaub ntug hauv paus, mozzarella thiab lub caij nplooj ntoos hlav dos,' nws hais.

'Tseem muaj pov thawj tias lub tswv yim thauj khoom ua haujlwm, tab sis tej zaum tsuas yog peb mus rau plaub hnub ua ntej kev sib tw, 'Leckie hais. 'Thaum yav dhau los kuv tau hnov txog cov neeg ncaws pob sib tw nrog kua txiv beetroot hauv lawv lub raj mis haus, tab sis qhov ntawd yog qhov tsis tsim nyog rau kev sib tw luv luv, tshwj xeeb tshaj yog tam sim no koj tuaj yeem tau txais nitrate-infused gels uas muaj ntau lub palatable. Muaj ntau lub tuam txhab uas muab 70ml ntawm cov kua txiv hmab txiv ntoo los yog nitrate nws tus kheej mus rau hauv lub zog gels.' Cov no suav nrog SiS thiab Zipvit, nrog rau Beet It, uas muaj 0.4g ntawm nitrate ib txhaj tshuaj lossis bar.
'Qhov no yog qhov siab tshaj plaws ntawm cov tshuaj nitrate hauv cov kua ntim tsawg tshaj plaws, 'hais tias Andy Jones, tus kws tshawb fawb kis las ntawm Exeter University uas tau coj nws txoj kev tshawb fawb rau beetroot.'Peb pom qhov txo qis hauv cov nqi oxygen ntawm kev tawm dag zog thiab peb cov kev kawm tuaj yeem mus ntev dua ntawm kev siv zog. Natural dietary nitrate yog ib qho ntawm cov khoom noj khoom haus kis las ntawm lub xyoo caum.'
Txawm li cas los xij koj coj nws, muaj ib yam uas Mitchell tau meej meej: 'Nws tsuas yog ntshav zoo veg.' Apollo yuav tsa ib khob kua txiv beetroot rau qhov ntawd.
